PtFeCoNiCu high-entropy alloy showed low overpotentials of 10 mV for HER and 164 mV for OER, indicating strong catalytic activity.
Electrocatalytic activity was enhanced through charge redistribution among mixed elements, stabilizing key intermediates.
Synthesis involved transient high-temperature shock method using carbonized wood as a substrate for high-entropy alloys.
Results imply great potential for efficient water electrolysis in hydrogen production with lower energy requirements.
